A:
The javascript menu frame wasn't developed as Dreamweaver/Frontpage extension,
BUT you can use it as standard javascript files. To install the javascript menu frame
into your html page:

1. open the page in Dreamweaver/Frontpage
2. open html source code of the page in your editor
3. add several rows of code (<script> tags), For info see:
